Cell Culture - Essay Example The number of giant cells should be low and fixed (MSUM, n.d.). The cell line selected for the study is rat coronary artery adventitial fibroblasts (Jenkins et al., 2007). The advantage of this selection is the fact that these cells have an important role in developing arteriosclerosis and plaque development (Jenkins et al., 2007), they divide rapidly and can differentiate into myofibroblasts (Jenkins et al., 2007) so those cells and their role in cardiovascular diseases can also be studied by the same culture instead of culturing the cells separately. Also, the culture permits the sole role of fibroblasts to be studied without the influence of other cells on them (Jenkins et al., 2007). The limitation of this cell line is that they have not been studied much before (Jenkins et al., 2007), so their response to different stimuli has not yet been fully determined (Jenkins et al., 2007); therefore, they might show unexpected behavior during

It is noteworthy that forcefully testing the worker will amount to a violation of the independence and privacy rights, which may attract legal proceedings. The ethical problem occurring in the case is associated with a locus of authority issue. This is because the supervisor upon being informed that the worker behaved in a drunken manner decided to identify with him the signs he also outwardly observed (Towsley-Cook & Young, 2007, p. 51). The supervisor reminded the worker that according the substance abuse policy, his conduct is a ground for drug testing. The supervisor acting within authority requests that the employee undergo a blood test, which he refuses. The supervisor then remains with the dilemma whether to force the worker to take the test or to send him away from duty, or whether to allow him to continue working. This is a critical case of a locus of authority issue (Towsley-Cook & Young, 2007). However, the supervisor can still manage to handle the situation by barring the worker from attending to patients. This conduct also amounts to the ethical dilemma for the supervisor. This is because while ordering the employee to take the test, the supervisor is already aware that the worker might be having health
